Abstract:

We report on the measurement of inclusive, non-prompt, and prompt J/$\psi$-hadron correlations by the ALICE Collaboration at the CERN Large Hadron Collider in pp collisions at a center-of-mass energy of $13~\text{TeV}$. The correlations are studied at midrapidity ($|y| <~ 0.9$) in the transverse momentum ranges $p_{\rm T} <~ 40~\text{GeV}/c$ for the J/$\psi$ and $0.15 <~ p_{\rm T} <~ 10~\text{GeV}/c$ and $|\eta|<~0.9$ for the associated hadrons. The measurement is based on minimum bias and high multiplicity data samples corresponding to integrated luminosities of $L_{\text{int}} = 34~\text{nb}^{-1}$ and $L_{\text{int}} = 6.9~\text{pb}^{-1}$, respectively. In addition, two more data samples are employed, requiring, on top of the minimum bias condition, a threshold on the tower energy of $E = 4$ and $9~\text{GeV}$ in the ALICE electromagnetic calorimeters, which correspond to integrated luminosities of $L_{\text{int}} = 0.9~\text{pb}^{-1}$ and $L_{\text{int}} = 8.4~\text{pb}^{-1}$, respectively. The azimuthally integrated near and away side yields of associated charged hadrons per J/$\psi$ trigger are presented as a function of the J/$\psi$ and associated hadron transverse momentum. The measurements are discussed in comparison to PYTHIA calculations.
